NAME

       range_str4inbuf - range check for string in buffer

SYNTAX

       #include <rangecheck.h>

       int range_str4inbuf(const void* buf,size_t len,const void* string);

DESCRIPTION

       range_str4inbuf  checks  that  the zero terminated UTF-32-string starting at string starts
       and ends within the buffer buf[0..len-1].

       If the string is not 0-terminated but the length is known beforehand, use range_arrayinbuf
       instead.

RETURN VALUE

       If the buffer is implausible (buf is NULL or buf+len has an integer overflow), return 0.

       If string points before or after the buffer, return 0.

       If there is no zero terminator within the buffer, return 0.

       Otherwise, return 1.
